Proportional Directional Valve 4WRZE10W8-25-7X/6EG24ETK31/F1D3M - Bosch Rexroth R901231829

The 4WRZE10W8-25-7X/6EG24ETK31/F1D3M combines a 4...20 mA current input with internal pilot supply and internal return. Piping is therefore limited to P, T, A and B. At 25 l/min nominal flow, spool symbol W8 and 315 bar operating pressure, this size 10 unit is laid out for smaller control axes.

Benefits

• Command value 4...20 mA for controllers with a current output, no extra converter.
• Internal pilot supply and internal return remove the X and Y lines.
• 25 l/min nominal flow, maximum flow 170 l/min at 315 bar operating pressure.
• On-board electronics, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Spool symbol W8, 3 switching positions, 4 ports, mounting pattern ISO 4401-05-05-0-05.
• Weight 9.2 kg, NBR seals, UKCA conformity.

Application

The version suits compact control axes in environments with long signal runs where a current signal is required. Port P must be permanently pressurised because the pilot stage draws from it. The return line additionally carries the pilot flow.
